摘要:Hydroxybenzaldoxime O-ethers of the formula ##STR1## in which R 1 represents alkyl, n are obtained by a process in which a tert.-butoxy-benzaldoxime of the formula ##STR2## is reacted with alkylating agents of the formula n n R.sup.1 --X n n in which n R 1 has the abovementioned meaning and n X represents halogen or OSO 2 OR 1 , n wherein n R 1 again has the abovementioned meaning, n in the presence of a strong base and phase transfer catalyst and in the presence of a diluent at temperatures between 0° C. and 50° C., and the products are then treated with anhydrous acid at temperatures between 0° C. and 50° C., n Hydroxybenzaldoxime O-ethers can be used as intermediate products for the synthesis of compounds with a fungicidal, insecticidal and antimycotic activity. The tert.-butoxy-benzalodoxime starting material is a new compound.

摘要:The present invention relates to a process for producing an optically active 2-substituent-oxy-3-(4-substituent-oxyphenyl)propionic acid derivative which comprises stereoselectively reducing an 2-oxo-3-(4-substituent-oxyphenyl)propionic acid by an enzyme and subjecting the thus-obtained optically active 2-hydroxy-3-(4-substituent-oxyphenyl)propionic acid to esterification of the carboxyl group according to need, then to alkylation of the hydroxyl group and, if necessary, to deprotection of an ether type protective group. The present invention may make it possible to produce an optically active 2-substituent-oxy-3-(4-substituent-oxyphenyl)propionic acid derivative, which is useful as intermediates for the synthesis of medicinal compounds, efficiently, in a simple and easy manner, and commercially advantageously.
